ALKALINE AQUEOUS FERRIC IRON SALT SOLUTION ELECTROLYTES AND BATTERIES MADE THEREFROM

An electrochemical cell is disclosed. The electrochemical cell comprises an anode side, a cathode side, a separator, and an alkaline aqueous ferric iron salt solution. The alkaline aqueous ferric iron salt solution may be either the catholyte or the anolyte, depending on the electrochemical half-reactions that define the electrochemical cell. The alkaline aqueous ferric iron salt solution comprises one or more anionic ferric iron-carbonate complexes.
